IPMP Addressing

You can configure IPMP failure detection on both IPv4 networks and dual-stack, IPv4 and IPv6 networks. Interfaces that are configured with IPMP support two types of addresses:

IPv4 Test Addresses

In general, you can use any IPv4 address on your subnet as a test address. IPv4 test addresses do not need to be routeable. Because IPv4 addresses are a limited resource for many sites, you might want to use non-routeable RFC 1918 private addresses as test addresses. Note that the in.mpathd daemon exchanges only ICMP probes with other hosts on the same subnet as the test address. If you do use RFC 1918-style test addresses, be sure to configure other systems, preferably routers, on the network with addresses on the appropriate RFC 1918 subnet. The in.mpathd daemon can then successfully exchange probes with target systems. For more information about RFC 1918 private addresses, refer to RFC 1918, Address Allocation for Private Internets.

IPv6 Test Addresses

The only valid IPv6 test address is the link-local address of a physical interface. You do not need a separate IPv6 address to serve as an IPMP test address. The IPv6 link-local address is based on the Media Access Control (MAC ) address of the interface. Link-local addresses are automatically configured when the interface becomes IPv6-enabled at boot time or when the interface is manually configured through ipadm.

For more information on link-local addresses, refer to Link-Local Unicast Address in System Administration Guide: IP Services.

When an IPMP group has both IPv4 and IPv6 plumbed on all the group's interfaces, you do not need to configure separate IPv4 test addresses. The in.mpathd daemon can use the IPv6 link-local addresses as test addresses.
